Answer:

  sum = ∑[n=1,5] 4^(n-4)

Step-by-step explanation:

First of all, you need to be able to describe the n-th term.

Here, we  have ...

  term #: 1, 2, 3, 4, 5

  value: 4^-3, 4^-2, 4^-1, 4^0, 4^1

That is, the exponent of 4 is 4 less than the term number. So, the n-th term is 4^(n-4). The sum of the 5 terms shown is then ...

  [tex]\displaystyle sum=\sum_{n=1}^5{4^{n-4}}[/tex]

Answer:

0.625

Step-by-step explanation:

Given :

Ambell company uses or procures batteries from two manufacturers.

The life of a battery in critical tool is at = 32 hours

Ambell uses 70% of its batteries from manufacturer 1 and out of that 90% batteries lasts for about 40 hours.

Similarly, 75% of the batteries procured from the manufacturer 2 lasts for about 40 hours.

Therefore, the probability that a battery is form manufacturer 1 is :

[tex]$\frac{0.4 \times 0.25}{(0.6 \times0.1)+(0.4 \times 0.25)}$[/tex]

= 0.625

Yes, 68.25 is near the top of the confidence interval.

Yes, the value of 68.25 is a number in the confidence interval.

Yes, 68.25 is much higher than the sample mean of all three-year-old thoroughbred racehorses, which was 65.2 inches.

No, the value of 68.25 is a number in the confidence interval.

No, the horses that run in the Kentucky Derby are a subset of all three-year-old thoroughbred racehorses

Answer:

No , the value of 68.25 is a number in the confidence interval.

Step-by-step explanation:

The confidence interval gives a range if values which is used in establishing the significance of an hypothesis. If the true mean falls within the confidence interval drawn, then our finding is insignificant and the null hypothesis will stand. However, if the true mean does not fall within the interval, then our result is considered significant and the null is thus rejected.

Since true mean exists within the confidence interval, then we conclude that the sample does not provide convincing evidence that three-year-old thoroughbred racehorses are, on average, shorter than those that run in the Kentucky Derby

a) The distance between the two cities is 1500 miles

b) The distance between the two national parks on the map is 4.5 cm

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The scale on the map is

3 cm : 500 miles

a)

Let the distance between the 2 cities be = A

Now , the equation is

When the distance between the 2 cities is 500 miles , the scale on the map is 3 cm

So ,

3 cm = 500 miles

9 cm = 3 x 3 cm

9 cm = 500 x 3 miles

        = 1500 miles

Therefore , the distance between the two cities is 1500 miles

b)

The distance between the two national park is 750 miles

Now , the equation is

When the distance between the 2 cities is 500 miles , the scale on the map is 3 cm

So ,

500 miles = 3 cm

1 mile = 3 / 500 cm

750 miles = ( 3 x 750 ) / 500 cm

750 miles = 3 x 1.5 cm

                 = 4.5 cm

Therefore ,

The distance between the two national parks on the map is 4.5 cm

Hence , a) The distance between the two cities is 1500 miles

b) The distance between the two national parks on the map is 4.5 cm

Answer:

Yes, the dog food will last a whole week

Step-by-step explanation:

1 pound=16 ounces, so

10 pounds=10*16=160 ounces.

There are 7 days in a week, so if Laura feeds her dogs 22 ounces per day, she will need 7*22=154 ounces to last a whole week.

She buys 160 ounces, which is greater than 154, so yes.

Answer:

Yes, the food will last the whole week

Step-by-step explanation:

10 pounds is 160 ounces. If you multiply 22 by 7 you'll get 154.

Answer:

[tex]46500 \pm 1.74\frac{10200}{\sqrt{18}}[/tex]

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.74

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.74\frac{10200}{\sqrt{18}}[/tex]

Confidence interval:

Sample mean plus/minus margin of error. So

[tex]46500 \pm 1.74\frac{10200}{\sqrt{18}}[/tex]

Answer:

9 boxes

Step-by-step explanation:

The number of boxes that has the same number of marbles is 9.

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The total number of marbles.

= 55 + 143

= 198

The number of boxes where each box has the same number of marbles.

= 198 / 22

= 9

Where each box will have 22 marbles.

Thus,

The number of boxes is 9.

Answer:

In the long run there are 0.02647 machines in the system queue.

Step-by-step explanation:

From the equation of the Finite Population Model of form M/M/1 with a finite source ,the average number of fax machines in the system to be maintained is given as :

[tex]L=\dfrac{\lambda^2}{\mu(\mu-\lambda)}[/tex]

Here

[tex]\lambda=\dfrac{Number\ of\ machines}{Time\ between\ Service}\\\lambda=\dfrac{3}{5\ hr}\\\lambda=0.6\ hr^{-1}[/tex]

So the equation becomes:

[tex]L=\dfrac{\lambda^2}{\mu(\mu-\lambda)}\\L=\dfrac{0.6^2}{4(4-0.6)}\\L=0.02647[/tex]

So in the long run there are 0.02647 machines in the system queue.
